Binlou Gao1†, Yang Zhong1†, Xiao Luo1, Jiacheng He1, Junxi Guo1, Xueying Wang1, Yikun Liu1, Licheng Tan*1, Yiwang Chen*1,2,3 Commercializing perovskite solar cells (PSCs) will likely require the scalable deposition of homogeneous perovskite films under ambient conditions. However, the spatially heterogeneous degradation of metastable perovskites during prolonged coating leads to nonuniformity. Here, we demonstrate spatiotemporally homogeneous crystallization of α- phase FAPbI3 (where FA is formamidinium) enabled by a phase- locking strategy that establishes a dynamically evolving, moisture- buffering intergranular network during large- area printing. This method prevents the premature degradation caused by ambient humidity, eliminating directional inhomogeneity. …
